An atmospheric immersive sim puzzle-horror game where you have 72 in-game hours to escape with your life. Solve challenging puzzles that require logical deduction during the day, survive assaults from hostile ghosts at night, and uncover the mystery behind Astor Manor.
Sepulchron
SteamSepulchron is a challenging puzzle game set in the eerie, abandoned Astor Manor. Test your logic, observation, and real-world knowledge as you explore by day and survive deadly ghostly threats by night. Use whatever you can find to defend yourself, and uncover the Manor’s secrets — before your 72 hours run out.
PUZZLES

Using physics as a base, Sepulchron's puzzles go beyond simply finding an item to act as a 'key' to solve them, as many puzzle games do. Found a sword, and there are ropes blocking your path? Don’t just 'interact' with it — swing that sword to cut the rope! Need to press something, but it won’t stay down? Maybe you need to place something heavy to weight it down. Use your logic and common sense of what an item should do to uncover secrets and solve the difficult puzzles scattered throughout Astor Manor.
GAMEPLAY

Ghosts and ethereal beings rise with the moon, and you must defend yourself against the evil that lurks in the dark. Either find and use weapons suited for combat with the best ammunition for each situation, or improvise and use whatever you can get your hands on — a chair, a sword from the wall, or even a teddy bear — to defeat your enemies and survive another night. And a word of warning: These sneaky ghosts change tactics every time you play, so stay on your toes!
ATMOSPHERE

Unlike most horror games, Sepulchron relies on atmosphere over jump scares. Its day-and-night cycle creates a tense rhythm — calm days offer brief safety, while nights bring real danger. Light becomes your lifeline, making fuel and illumination management key to survival. And pay attention for secrets: There is always more than a way to move foward.
